Leave the science to us

Independent lab testing and dose verification

By Brewlune · Updated August 31, 2026

Yes — Brewlune is third-party tested. Every batch is tested by independent, accredited laboratories for heavy metals, mycotoxins, and pesticides, with potency checks on caffeine and per-species beta-glucans. Leave the science to us: we work with independent labs and our suppliers' own analytical programs so that what the label says is what the bag holds.

Testing isn't a badge for us — it's the product. Brewlune prints the exact milligrams of every mushroom species on the front of every bag, plus per-species beta-glucan minimums, and holds every batch to those numbers. We stay on top of the current research on functional mushrooms so every claim on the label has something real behind it.

Certificates of analysis are the receipts, and here is exactly where that stands: samples from the current batch are with Clean Label Project's independent testing program now, results publish on this page the day they issue, and every batch's COA lands here with the batch number on your bag matching the report.

How we test

Every batch, the same panel, by independent accredited laboratories.

Heavy metals

Lead, arsenic, cadmium, and mercury — screened in every batch, because functional mushrooms concentrate what they grow in.

Mycotoxins

Mold-produced toxins that can ride along with any dried agricultural ingredient. Tested per batch, across coffee and extracts alike.

Pesticides

Screened across the finished blend — not just the individual ingredients before they meet.

Potency

Caffeine and per-species beta-glucans, verified against the numbers printed on the front of the bag.

What we print, we stand behind

Most brands in this category sell a proprietary blend and a promise. Brewlune prints the exact milligrams of every species on the front of the bag. Those numbers come from the formulation itself — the extracts are 100% extract powders, so grams of input equal label milligrams — and the testing program holds every batch to them.

Reports

Samples from the current batch are with Clean Label Project's independent testing program; results publish here the day they issue. Until then, the testing documentation available today is the suppliers' own published specifications, linked below. Batch COAs land on this page as batches clear, batch number on your bag matching the report:

Questions people actually ask

+Is Brewlune independently lab tested?

Yes. Every batch is third-party tested by independent, accredited laboratories for heavy metals, mycotoxins, and pesticides, with potency checks on caffeine and per-species beta-glucans. The current batch is with Clean Label Project's independent testing program; its COA publishes on this page when results issue.

+What does Brewlune test for?

Heavy metals (lead, arsenic, cadmium, and mercury), mycotoxins, and pesticides in every batch, plus potency verification of caffeine and per-species beta-glucans against the doses printed on the bag.

+Which laboratory tests Brewlune products?

We work with independent, accredited laboratories and our suppliers' analytical programs; the current batch is with Clean Label Project. Each batch's COA identifies the laboratory and methods used for that batch — the first publishes here when results issue.

+Can I see Brewlune's certificates of analysis?

Yes — the testing documentation behind every extract is published and linked on this page: our suppliers' third-party testing and per-species beta-glucan specifications, at their source. Batch-level COAs publish on this page as they issue — samples from the current batch are with Clean Label Project's independent testing program now, and the batch number on your bag matches the report.

+How do I know the doses on the bag are real?

They're printed on the front, which is the point. The extracts are 100% extract powders, so grams of input equal label milligrams directly, and testing verifies beta-glucan content per species against the supplier minimums.

+Are Brewlune's mushrooms fruiting-body extracts?

Yes, in every blend: the extracts are Real Mushrooms products, produced by Nammex, stated by the supplier as fruiting-body-only with no mycelium-on-grain, with published beta-glucan minimums per species. The suppliers, origins, and certifications for every component are on the sourcing page.

Every supplier behind these components is named, with origins and certifications, on the sourcing page. Per-blend doses live on the dosage comparison page, and the specs comparison against Four Sigmatic, RYZE, and Everyday Dose puts the caffeine and extract-type numbers side by side. Testing is also half the answer to the question buyers actually start with — is mushroom coffee worth it — because a claim is only worth paying for if someone checks it.
